The Monitor XT70 makes its grand entrance as the evolution of the classic Polk Audio Monitor series. A passive floor-standing loudspeaker that effortlessly handles the left or right channel of your home theater setup, the Monitor XT70 is capable of reproducing frequencies as low as 35Hz. It accomplishes such a feat by utilizing two Dynamic Balance 6.5" woofers. Meanwhile, two passive 8" radiators help extend the low-end further without adding undue bulk. Trebles are handled by a stunning Terylene dome tweeter, which supplies vivid sound all the way up to 40kHz. It’s a sonic experience that Sweetwater audio fanatics believe must be experienced to be truly understood. As you’ll read below, there’s so much to like about the Monitor XT70.
